Inferior Olive of the Cat: Intracellular Recording

Science, 1967
The action potential evoked from inferior olivary neurons of the cat by orthodromic, antidromic, or intracellular stimulation has a large prolonged depolarization, frequently with several superimposed smaller spikes. The all-or-nothing unitary response appears to be a property of the cell, and the later spikes are not secondary to synaptic excitation ...

Peptide localization in the mouse inferior olive

Journal of Chemical Neuroanatomy, 1997
The inferior olivary complex is the sole source of climbing fibers to the cerebellar cortex. Physiologically these afferents have been shown to have a powerful excitatory effect on their target neurons, namely Purkinje cells. Thus, any modulation of olivary firing rate or responsiveness will alter Purkinje cell firing and ultimately cerebellar function.

Yaw direction neurons in the cat inferior olive

Journal of Neurophysiology, 1988
1. Single units that responded to yaw rotation were recorded extracellularly in the caudal inferior olive (IO) of barbiturate-anesthetized cats. Of 276 neurons, 55 responded reliably to yaw, and extensive quantitative data were recorded from 25. 2.

Inferior olive and oculomotor system

2006
Three subnuclei within the inferior olive are implicated in the control of eye movement; the dorsal cap (DC), the beta-nucleus and the dorsomedial cell column (DMCC). Each of these subnuclei can be further divided into clusters of cells that encode specific parameters of optokinetic and vestibular stimulation.

Inferior Olive and the Saccadic Neural Integrator

1995
Following a lesion of the inferior olive, spontaneous saccades are characterised by a backward postsaccadic drift. When performed in light, this drift has a time constant of 100– 150ms and after a few tens of ms, it gradually slows down to reach a steady level under a drive of the optokinetic reflex.

Red Nucleus Stimulation Inhibits Within the Inferior Olive

Journal of Neurophysiology, 1998
Horn, K. M., T. M. Hamm, and A. R. Gibson. Red nucleus stimulation inhibits within the inferior olive. J. Neurophysiol. 80: 3127–3136, 1998. In the anesthetized cat, electrical stimulation of the magnocellular red nucleus (RNm) inhibits responses of rostral dorsal accessory olive (rDAO) neurons to cutaneous stimulation.

HYPERTROPHY OF THE INFERIOR OLIVES IN THE CAT

Journal of Neuropathology and Experimental Neurology, 1962
In this paper 2 cases of olivary neuronal hypertrophy in the cat were described. They developed following ablation of the cerebellum, the central nuclei included. In one, in which one half of the cerebellum only was ablated totally and the other only partially, the most extensive distribution of hypertrophic neurons was contralateral to the total ...

UNUSUAL RESPONSE OF THE INFERIOR OLIVE TO GLIOMAS

Journal of Neuropathology and Experimental Neurology, 1962
In 31 of 78 cases of gliomas of the brain stem the lesions involved the olivary nuclei. Eighteen of the lesions were bilateral. In 3 of the cases of bilateral tumors in which the lesions extended partly into the olive from the rostral end of that structure, the gray matter of the olivary nuclei had a diffuse, enlarged and unusual cellular appearance ...

Hypertrophy of the inferior olives

Zeitschrift f�r Neurologie, 1973
A report is given on 29 cases of olivary hypertrophy of different origin with special reference to the quality and topistic distribution of olivary degeneration in relation to the dating and site of the primary lesion. All except one case of hypertrophic degeneration of the inferior olive resulted from injury to the dentato-olivary pathway; 13 were ...

Influence of inferior olive on flexor reflex activity

Experimental Brain Research, 1986
In Wistar rats we have studied the effect of inferior olive lesion or activation on the threshold of a flexor reflex elicited by a nociceptive stimulus applied to the hindpaw. When the inferior olive is lesioned by means of 3-acetylpyridine, the threshold value is significantly decreased. A recovery occurs in 3-4 weeks.
